Ajax will be without Tagliafico on the left wing for the return leg. He got a yellow card and is suspended for the 2nd match. Lasse Schone limped off because of an injury, I don't know how serious that is. Ajax is also still fighting with PSV for the league title so they can't afford to play badly in the league meaning they have to filed a strong lineup during the weekend. Juventus on the other hand has an 18 points advantage in the league and will be playing SPAL. At least 7 starters will be rested during that match and that could end up being the advantage the Juve needs to qualify for the next round.
